Abstract
A network node is provided. The network node includes processing circuitry configured to estimate spatial transmission information, STI, for each of a plurality of wireless devices, and determine spatial separability among the plurality of wireless devices based at least in part on the estimated STI for each of the plurality of wireless devices. The processing circuitry is further configured to cause scheduling of the plurality of wireless devices on the same communication resources based at least in part on the determined spatial separability.
Claims29
A network node, comprising:
- processing circuitry configured to:
- estimate spatial transmission information, STI, for each of a plurality of wireless devices serviced by a plurality of network nodes;
- determine spatial separability among the plurality of wireless devices based at least in part on the estimated STI for each of the plurality of wireless devices;
- and
- cause scheduling of the plurality of wireless devices on the same communication resources based at least in part on the determined spatial separability, the scheduling of the plurality of wireless devices on the same communication resources includes causing each of the plurality of network nodes to precode transmission on the same communication resources.
A method performed by a network node, the method comprising:
- estimating spatial transmission information, STI, for each of a plurality of wireless devices serviced by a plurality of network nodes;
- determining spatial separability among the plurality of wireless devices based at least in part on the estimated STI for each of the plurality of wireless devices;
- and
- causing scheduling of the plurality of wireless devices on the same communication resources based at least in part on the determined spatial separability, the scheduling of the plurality of wireless devices on the same communication resources includes causing each of the plurality of network nodes to precode transmission on the same communication resources.
A network node, comprising:
- processing circuitry configured to:
- estimate spatial transmission information, STI, for each of a plurality of wireless devices serviced by a plurality of network nodes based at least in part on uplink reception from each of the plurality of wireless devices, the estimated STI corresponding to an angle of arrival, AoA, with respect to a connected network node;
- determine spatial separability among the plurality of wireless devices based at least in part on the estimated STI for each of the plurality of wireless devices;
- and
- cause scheduling of the plurality of wireless devices on the same communication resources for multiuser multiple-input multiple-output, MU-MIMO, based at least in part on the determined spatial separability, the scheduling of the plurality of wireless devices on the same communication resources includes causing each of the plurality of network nodes to precode transmission on the same communication resources.
